Cyclone is no longer supported; the core research
project has finished and the developers have moved on to other things.
(Several of Cyclone's ideas have made their way into Rust.)
Cyclone's code can be made to work with some effort, but it will not build
out of the box on modern (64 bit) platforms).

Cyclone is available as a VM for 32-bit platforms.
See this blog post for how to get it.
